Let's denote the base of the triangular face as "b" and the height as "h." According to the given information, the height is one-half of the base, so we have:

h = (1/2) * b

The length of the tent is 1 ft more than the base, so the length can be represented as:

l = b + 1

The volume of a triangular prism is given by the formula:

Volume = (1/2) * base * height * length

Substituting the given values into the volume formula, we have:

20 = (1/2) * b * ((1/2) * b) * (b + 1)

Simplifying the equation:

20 = (1/4) * b^2 * (b + 1)

Multiplying both sides by 4 to eliminate the fraction:

80 = b^2 * (b + 1)

Rearranging the equation:

b^3 + b^2 - 80 = 0

To find the dimensions of the tent, we need to solve this cubic equation. However, finding the exact solution for a cubic equation can be quite involved. Instead, we can approximate the solution using numerical methods or use a calculator or software to find the approximate value of "b."

Let's assume a rounded value of "b" and calculate the corresponding values of "h" and "l" to verify if they satisfy the conditions:

Assuming b ≈ 4, we can calculate:

h = (1/2) * 4 = 2 ft

l = 4 + 1 = 5 ft

Now, let's calculate the volume using these values:

Volume = (1/2) * 4 * 2 * 5 = 20 ft^3

Since the volume matches the given volume of 20 ft^3, we can conclude that the tent dimensions are approximately:

Base (b) ≈ 4 ft

Height (h) ≈ 2 ft

Length (l) ≈ 5 ft

Please note that these values are approximations based on the assumption of b ≈ 4. For an exact solution, it would be necessary to solve the cubic equation.

Answer:

1. \(x^2-6x+8=0\)

2. \((x-4)(x-2)=0\)

3. \(x=4 \text{ and } x=2\)

4. \(x=4 \text{ and } x=2\)

Step-by-step explanation:

1. When using substitution all we do would be is substituse the y for a 3.

This leaves us with the equation:

\(3=-x^2+6x-5\)

Rewriting it we get:
\(0=-x^2+6x-8\)

or if we shift the 0 to the other side:

\(x^2-6x+8=0\)

2. In order to factor the equation we can use the butterfly method:

\(\left[\begin{array}{ccc}1&-4\\1&-2\end{array}\right]\)
So it factors out to:

\((x-4)(x-2)=0\)
You can also use the quadratic formula.

3. To find the solutions we just set each factor to 0
\(x-4=0\\\text{and}\\x-2=0\)
So the x-values would be:
\(x=4 \text{ and } x=2\)

4. To find the solution to the system we just plug in the values and it turns out to be the same numbers as before.

Step-by-step explanation:

triangle 1/2 base x height = area    45 x 4 = 180

the exact distance between the points T(13, 1.6) and V(5.4, 3.7) is approximately √62.17. This is the simplest exact form of the answer.

To find the distance between two points in a coordinate plane, we can use the distance formula. The distance formula is derived from the Pythagorean theorem and helps us calculate the straight-line distance between two points.

The distance formula is given as:
d = √((x₂ - x₁)² + (y₂ - y₁)²)

Let's find the distance between the points T(13, 1.6) and V(5.4, 3.7):

x₁ = 13
y₁ = 1.6
x₂ = 5.4
y₂ = 3.7

Using the distance formula, we have:
d = √((5.4 - 13)² + (3.7 - 1.6)²)

Simplifying the expression inside the square root:
d = √((-7.6)² + (2.1)²)

Calculating the squares:
d = √(57.76 + 4.41)

Adding the values inside the square root:
d = √(62.17)

Taking the square root:
d ≈ √62.17

Therefore, the exact distance between the points T(13, 1.6) and V(5.4, 3.7) is approximately √62.17. This is the simplest exact form of the answer.

Rounded to the nearest whole number, this means that about 7% of test takers scored higher than you.

The area of mathematics known as probability deals with numerical representations of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a larger range, a low standard deviation suggests that the values tend to be near to the mean (also known as the anticipated value) of the collection.

The standard deviation is a measure of how spread out the data is around the mean. In this case, the mean test score is 77, and the standard deviation is 8, so the data is spread out around the mean by 8 points.

Since you scored a 91 on the test, which is higher than the mean of 77, this means that you scored higher than the average test taker. To find the percentage of test takers who scored higher than you, we can use the standard normal distribution to find the area under the curve between your score and the highest possible score.

To do this, we first need to standardize your score by subtracting the mean and dividing by the standard deviation. This gives us (91 - 77) / 8 = 1.375.

We can then use a table of the standard normal distribution or a calculator to find the area under the curve between your score and the highest possible score. This area is approximately 0.9332, or about 93.3%.

Rounded to the nearest whole number, this means that about 7% of test takers scored higher than you.

The 12th mortgage payment is 23,998.11 pesos, which is calculated based on the loan amount, 2 years of accrued interest, and the monthly mortgage payment formula.

To calculate the amount of the 12th mortgage payment, we need to break down the steps involved:

1. Calculate the loan amount after 2 years of accruing interest:

The loan amount after 2 years will be the sum of the initial loan amount and the accrued interest. Since the interest is compounded semi-annually at a rate of 15%, the formula for calculating the future value (FV) of the loan after 2 years is:

FV = PV * (1 + r/2)²ⁿ

Where PV is the present value (loan amount), r is the interest rate, and n is the number of compounding periods.

In this case:

PV = 2,000,000 pesos

r = 15% = 0.15

n = 2 years

FV = 2,000,000 * (1 + 0.15/2)²²

FV = 2,000,000 * (1 + 0.075)⁴

FV ≈ 2,479,095.31 pesos

2. Calculate the monthly mortgage payment for the first 5 years:

The monthly mortgage payment during the first 5 years is half of the payments from the 6th to the 30th year. Since the mortgage is for 30 years, there are 360 monthly payments.

The formula for calculating the monthly mortgage payment is:

PMT = PV * (r/12) / (1 - (1 + r/12)⁽⁻ⁿ⁾)

Where PMT is the monthly payment, PV is the loan amount, r is the monthly interest rate, and n is the number of months.

In this case:

PV = 2,479,095.31 pesos (calculated in step 1)

r = 12% = 0.12

n = 360 months (30 years)

PMT = 2,479,095.31 * (0.12/12) / (1 - (1 + 0.12/12)⁽⁻³⁶⁰⁾)

PMT ≈ 23,998.11 pesos

3. Calculate the amount of the 12th mortgage payment:

Since the first monthly mortgage payment is made exactly 2 years after the loan is requested, the 12th mortgage payment corresponds to the payment made in the 13th month.

Therefore, the amount of the 12th mortgage payment is approximately 23,998.11 pesos.

In conclusion, the amount of the 12th mortgage payment is approximately 23,998.11 pesos. This calculation takes into account the initial loan amount, accrued interest over 2 years, and the monthly mortgage payment formula. It is important to note that the calculations provided are based on the information and assumptions given in the question.

The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.

1/8

The probability of getting a head or a tail when flipping a coin is 1/2.  

Therefore, the probability of getting two heads when tossing two coins is 1/2 x 1/2 = 1/4.

The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.

Since each person is tossing three coins, the probability that they both obtain the same number of heads is 1/8.

The probability of getting n heads when tossing n coins is 1/2^n. Therefore, the probability of getting the same number of heads when two people toss n coins is 1/2^n. This means that if two people each toss a coin, the probability that they both get heads is 1/4; if they each toss two coins, the probability that they both get two heads is 1/16; if they each toss three coins, the probability that they both get three heads is 1/64; and so on.

Nina planted 24 pink and purple tulips. If 1/3 of the tulips were pink. Nina planted 8 pink tulips and 16 purple tulips.

Nina planted a total of 24 pink and purple tulips. Given that 1/3 of the tulips were pink, we can use this information to determine the number of pink tulips planted.

To find the number of pink tulips, we need to multiply the total number of tulips by the fraction that represents the proportion of pink tulips. In this case, the fraction that represents the proportion of pink tulips is 1/3, which can also be expressed as 8/24 (since 1/3 is equivalent to 8/24).

To find the number of pink tulips, we can multiply the total number of tulips (24) by the fraction 8/24, which gives us the answer:

Number of pink tulips = 24 x 8/24 = 8

Therefore, Nina planted 8 pink tulips. We can also find the number of purple tulips by subtracting the number of pink tulips from the total number of tulips, which gives us:

Number of purple tulips = 24 - 8 = 16

The given mathematical expressions consist of several functions and operations. Let's break them down one by one.

h(2) = (1+2z+32²) (5z + 82²-2³):

In this expression, we have a function h(2) defined as the product of two binomial terms. The first term is (1+2z+32²), and the second term is (5z + 82²-2³). To evaluate h(2), substitute the value 2 for z and perform the arithmetic calculations using the given values for the constants.

R(w) = 3w + w² + 2w² + 1:

Here, we have a function R(w) defined as a polynomial expression. It consists of two terms: 3w and w², along with another term 2w² and a constant term 1. To simplify R(w), combine like terms by adding the coefficients of similar powers of w.

g(z) = 10 tan(z) - 2 cot(z):

The function g(z) involves trigonometric functions. It is defined as the difference between 10 times the tangent of z and 2 times the cotangent of z. To evaluate g(z), substitute the given value for z and compute the trigonometric functions using the given formulae.

g(t) = (4t²3t+2)-²:

In this expression, we have a function g(t) defined as the reciprocal of the square of a polynomial. The polynomial is (4t²3t+2), which involves terms with different powers of t. To evaluate g(t), square the polynomial and take its reciprocal.

g(z) = 327 - sin(2²+6):

Here, we have another function g(z) defined as the difference between the constant 327 and the sine of an expression inside the parentheses. The expression inside the sine function is (2²+6), which simplifies to 4+6=10. To evaluate g(z), calculate the sine of 10 and subtract it from 327.

y = √(1-8z):

The final expression defines a variable y as the square root of the difference between 1 and 8 times z. To find y, substitute the given value of z and compute the expression inside the square root, followed by taking the square root itself.

The entire area of the sailboat is 60cm²

Step-by-step explanation:

You can find the area of this shape by breaking it down into simpler shapes and adding up their individual areas.

In this case, the areas we'll use are the rectangle at the bottom, and the pair of triangles at the top.

Because the two triangles can be put together to form a single triangle, we don't need to measure them independently.  We can simply take the total length of their bases, multiply it by their height, and divide by two.  This follows the rule that the area of a triangle is equal to the area of the square that contains it divided by two.

(2cm + 3cm) × 6cm

= 5cm × 6cm

= 30cm²

The rectangle's area is of course equal to its width times its height, so we can say:

2.5cm × 12cm

= 30cm²

The total area of the shapes then is 30cm² + 30 cm², giving us a total area of 60cm²
